I hate the trend for having big TVs myself, but I don't really care where people put them.I don't see how they would dominate a room more by being on the wall, they dominate the room because they are black and enormous, not because they are on the wall. (I wonder if in the future you will be able to have TV's that match the colour of the wall behind them when they are switched off...)
I'm sure that programme makers now expect everyone to have massive TVs, and they shoot their programmes accordingly, which is a pain for people with small tvs.
We have a small flat screen TV (19 inch), and it's quite far away from the sofa due to the shape of our living room.
If we are watching a modern programme, and there is something like a letter shown on screen we can NEVER read what it says - it's too fleeting and small. We don't have that problem with older programmes, the camera stays long enough for your eyes to focus.
Subtitles can also be difficult sometimes.
I'm sure sport is shot from further away too, and it doesn't really suit our size of screen.
Anyway, we can't afford a new, bigger one, so will just have to carry on straining our eyes, or pushing the sofa into the middle of the room so we don't miss anything
